1.	In which atom, the outermost electron can have the following set of quantum numbers?n = 3, l = 0, ml = 0, ms = -\(\frac{1}{2}\)
Answer» n = 3,l = 0, \(\therefore\) Orbital is 3s m_l = 0, Means only one electron is present in 3s m_s = -\(\frac{1}{2}\) \(\therefore\) Electronic configuration of atom is – 1s² , 2s²2p⁶ , 3s¹ \(\therefore\)The atom is sodium (Na)

In which atom, the outermost electron can have the following set of quantum numbers?n = 3, l = 0, ml = 0, ms = -\(\frac{1}{2}\)

Answer»

n = 3,l = 0, \(\therefore\) Orbital is 3s

m_l = 0, Means only one electron is present in 3s

m_s = -\(\frac{1}{2}\)

\(\therefore\) Electronic configuration of atom is –

1s² , 2s²2p⁶ , 3s¹

\(\therefore\)The atom is sodium (Na)
